Question

Please help me!

Answer 1

w= (82.9/d)^3
Find the inverse of the model.

Answer 2

replace w by d . and solve for w you can get inverse

Answer 3

but in word problems u can't change the variables or you'll get a messed up answer

Answer 4

you must do that if you want to get the inverse function. even I exchange the variables but at the end up, I still have w =....something.

Answer 5

but i am trying to get d

Answer 6

ok, I don't know what are you studying in class about the inverse function. mine is: d = (12.9)^3/w^3.---> w^3 = (82.9)^3/d ---> \[w=82.9\sqrt[3]{\frac{ 82.9 }{ d }}\]

Answer 7

that is the inverse of original one. believe or not, depend on you.
